Unit 1 Vocabulary - Algebra 2

Front

Sequence / Secuencia

Back

Ordered list of objects / numbers.

Front

Function / Función

Back

A function is a rule that assigns to each input value exactly one output value.

Front

Parabola / Parábola

Back

A plane curve (similar to an U shape) that is mirror-symmetrical across the y-axis.

Front

Axis

Back

The axis of symmetry of a parabola is a line that divides the parabola into two mirror-image halves.

Front

Vertex / Vértice

Back

The point where the parabola changes direction. Can be either the highest (maximum) point or the lowest point (minimum) on the curve.

Front

Transformation / Transformación

Back

The right/left, up/down movement, or compression/stretching of the parental function.

Front

Compression / Compresión

Back

The graph is made narrower (horizontally) or shorter (vertically).

Front

Reflection / Reflección

Back

Flips a graph over a line, creating a mirror image. Reflections can be either vertical (across the x-axis) or horizontal (across the y-axis).

Front

Translation / Translación

Back

Shifting the graph horizontally (to the right or to the left) or vertically (up or down) or both.

Front

Maximum / Máximo

Back

The maximum value of a parabola is the highest y-coordinate it reaches, which occurs at the vertex when the parabola opens downwards.
